de Sitter Excited State in Heterotic E_8 x E_8 Theory
Suddhasattwa Brahma, Keshav Dasgupta, Bohdan Kulinich +3
We devise a novel duality sequence to study late-time cosmology in the heterotic E_8 x E_8 setup of Horava and Witten with dynamical walls that are moving towards each other. Surpr…
Wheeler-De Witt equation and the Canonical Construction of the Glauber-Sudarshan States in Quantum Gravity
Keshav Dasgupta, Fang-Yi Guo, Bohdan Kulinich
Quantum gravity is fundamentally different from the non-gravitational quantum field theories in the sense that most of the techniques derived for the latter cannot be easily extend…
Glauber-Sudarshan States, Wave Functional of the Universe and the Wheeler-De Witt equation
Suddhasattwa Brahma, Keshav Dasgupta, Fangyi Guo +1
One of the pertinent question in the analysis of de Sitter as an excited state is what happens to the Glauber-Sudarshan states that are off-shell, i.e. the states that do not satis…
